Syntax

c = prism
c = prism(m)

Description

c = prism returns the prism colormap as a three-column array with the same number of rows as the colormap for the current figure (gcf). If no figure exists, then the number of rows is equal to the default length of 256. Each row in the array contains the red, green, and blue intensities for a specific color. The intensities are in the range [0,1], and the color scheme is a repeated sequence of the rainbow colors.

Sample of the prism colormap

c = prism(m) returns the colormap with m colors.

Create a scatter plot with the default colors.

x = [3.5 3.3 5 6.1 4 2];
y = [14 5.7 12 6 8 9];
sz = 100*[6 100 20 3 15 20];
c = [1 2 3 4 5 6];
scatter(x,y,sz,c,'filled','MarkerEdgeColor','k','MarkerFaceAlpha',.5);
xlim([1 7]);
ylim([1 16]);

Get the prism colormap array with six entries. Then replace the colormap in the scatter plot.

c = prism(6);
colormap(c);
